T0 ALL WHOM IT MAY' CONGERN:

Be it known that we, JAOB- H. HAWES, of Boston, in the county of 'Sutiollg and State of Massachusetts, i

and GEORGE H. BLISS, of`West Stockbridge, in the county of Berkshire, and State of Massachusetts, have invented certain new and useful Improvements in Belt-.Glasps and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a portion of this specification, in which- Figure 1 is a plan view of the outermost side of a belt-clasp constructed aocording to our invention.

Figure 2 is a longitudinal section of the said clasp,rshowing the manner'of using the same.

Figure 3 is a detached plan view of one portion f the same. x

Similar letters of reference indicate corresponding parts in all the figures.

The object of -this invention-is to .provide a belt-clasp which may -be manufactured at a very moderate cost, and which will not only serve to eie'ctually secure together the ends of the belt, but whichmay also be very .conveniently manipulated in connecting` the said ends, and, furthermore, by .the lemployment of wh-ich a smooth surface at'the inner side of the belt 'may be insured, in lorder to avoid any-inequality in the movement of the said belt upon the pulley. Y I The invention consists `in a clasp, constructed with external leaves and internal' lips, so combined as to clasp the ends of the belt between them; and, furthermore, in a spring-slip, having the lips just mentioned formed thereon, and capable of being readily secured -in or detached from the shell ofthe clasp, the objects named being, by these means, elieetually secured.' i

To enable Others to understand the nature and construction of our inventlon, we will proceed to'describc it w'ithreference to the drawings. Y

A represents the shell ofthe clasp, formed of a piece of stiff sheet metal, having its edge-portions folded over, as shown at a, in a position parallel with and at a suitable distance from its central or back part, b, as indicated more clearly in fig. 1, with a space, al, between them, the said edge-portions a, thus iolded over," constituting lcaves, the purpose of which will presently. herein appear. The central or back part, b, of the shell just described, is bulged outward' longitudinally at its middle, as shown at a', in order that alongitudnal recess maybe formed in the inner side of the'lsaid' back, for the reception of a. slip, B, shown more fullyl in g..3, and which consists: of asomewha't elastic strip'of sheet metal, vmade and shaped in its crossfs'ection as represented in fig. 2, and with its lateral edges serrated o r furnished withteeth, b', the said toothed or ser-A rated edges constituting lips, bl, which project downward at an angle when the slip is placed within the shell A, as hereinafter fully explained.

When the clasp is in use, the two ends o f thebelt are thrust through-the spacea', and folded inward over the leaves a, which being done, this vslipB is thrust into-the. shell A, and rests in the longitudinal recess, just described, in the inner side.of;the back thereof, in -such position that the two ends-fof the belt -C to'be jpined, -being folded inward oventhe edges ofthe leaves a, as just hereinbefore described, and brought between the said leaves andthe toothed or serrated edges of the spring-slip B, the elasticity of the-said slip will press the said edges downward upon the belt, and, the tension upon the two ends of the belt being equal, thesaid. tension, by drawing upon theaforesaid edges, will spring them slightly downward thusvcausing them to tightly hold and confine the ends of the belt within the clasp, one-half'of the strainexerted upon the clasp bythe belt beingbrne bythe lips I, and the others by theleaves a, over which the ends of the belt are folded, as just hereinbefore set forth.

When it is desired to unclasp or separate the ends of the belt, the slip B is pushed out fromtheshell A, whereupon the aforesaid ends may be readily .withdrawn from the latter.

What we claim as our invention,l and desire to secure byLetter's APatent,-isv

l 1. The clasp, constructed with`the leaves, a, and'internalflips, serving conjointly to hold the ends of the belt, substantially as herein set forth'. 'y

2. The detachable spring-slip B, constructed with the toothed lipsl, and arranged within the shell of the clasp, substantially as-an'd for the purpose' specied. l Y
